Abstract
We report for the first time (to our knowledge) a diode-pumped Nd:YAG laser emitting at based on the transition, generally used for a emission. Power of at has been achieved in cw operation with a fiber-coupled laser diode emitting at . Intracavity second-harmonic generation in the cw mode has also been demonstrated with power of at by using a nonlinear crystal. In our experiment, we used a crystal lens to complement the thermal lens of the laser rod, and we obtained good beam quality and high output power stability.
